My personal choice would be an ideal logic max 30/35kw. My reason for this is I believe that the 10 year warranty is amazing. I know other manufacturers have offered similar warranty to this but the price says it all. For such a competitive priced long warranty boiler I believe the manufacturing side speaks for itself. Who would offer a warranty for 10 years if they thought it would break down. Other added factors which persuade me to this particular boiler it the magnetic filter that is included and the customer care at ideal. I had never fit an ideal boiler before a customer asked me and I can honestly say I was that impressed I have now fit hundreds (along with other brands) and keep going back to ideal. One boiler once had a problem and I phoned technical on a Friday evening. They couldn’t assist so passed it to their engineers. One arrived at 11am Saturday morning and fixed the fault.

Ok - so this question can be rather ambiguous without a survey of the property. But, generally we would recommend a 28kw boiler for the job. This will supply ample hot water and run the heating system very efficiently. When looking for a new boiler always find out how much warranty the boiler comes with from the manufacturer. If the manufacturer is prepared to give you a good warranty then they must have confidence in their appliance, this is a good rule of thumb. Still today some manufacturers offer 2, 3, 4 and even 5 year warranties.......Look for one that offers 7 years plus! Also....check the warranty offered....parts and labour, parts only? And how many hoops are they going to ask you to jump through? Main dealer service only or any Gas Safe Registered installer? We recommend the Alpha Evoke 28kw, complete with an out of the box Alpha warranty of 7 years ( can increase ) and only hoop you have to jump through is to have your boiler serviced by any gas safe registered installer.

A 28kw combi boiler would likely be able meet the hot water demand as long as there is only one bathroom and sufficient mains water flow rate at the property. An engineer's survey would confirm this and if any system alterations need to be made to comply with Building, Gas & Electrical regulations.

In any situation it would be best to call on a time served engineer to conduct a site survey and answer a few questions regarding water usage and demands. In most cases in this type of property a 30kw boiler would give ample supply to meet the needs of a small family. There are many different manufacturers on the market and the choice is usually driven by budget. Worcester sit at the top of this at the most expensive, vaillant baxi sitting mid range and ideal at the lower end. Ideal seem to be a good option at the moment due to a long warranty. TanK plumbing would be happy to help with advise on the best boiler for your individual needs.

Most boiler manufactures offer large warranties now ranging from 5 to 12 years as long as the appliance is serviced each year by a gas safe registered engineer. I personally would recommend an Ideal Max 24 or 30kw boiler depending on how much hot water flow rate you required. The ideal boiler is cheaper than The Vaillant and the Worcester and off the same length of warranties. These boiler have been voted the best house builders boiler for the last 3/4 years running.

With so many options available on the market the choice is endless. Personally these days I think it comes down to warranty the customer wants out of a new boiler as you can have from 2 years up to 12 years manufactures warranty and as you know that has a big impact on the price. As for a 2-3 bed family home with running on a combi I would recommend between a Intergas or ideal boiler but this is the customers choice, we can only guide them in the right direction as price will makes all the difference when looking for new products.

Would depend on how many bathrooms/en-suite were in the dwelling which would affect the draw of hot water, thus a larger boiler might be required if property has more than one bathroom. But usually I would recommend a 24kw combi boiler Preferably a Worcester or a vaillant. Radiators not usually an issue for the smaller property

Heating wise a 24kw boiler would be fine. If the property has more than 1 shower attached to the hot water system then I would recommend the intergas boiler. Due to it's different design no other wall hung boiler can compete with the flow rate. To get a better flow rate then you'll need a higher powered boiler. The same would apply if the property has a bath. If the property only has electric showers then a 24kw will do.

There isn’t a straight forward answer to this. An engineer would need to survey the property and discuss with the customer their hot water needs/consumption. Much of it also depends on the cold water volume coming into the house. Best answer, call in an engineer to discuss your options.

In the murky world of plumbing and heating there is never a straightforward answer! Some of the stipulations needed to decide on what boiler is best for the property are as follows. How many bathrooms are in the property? How many inhabitants are in the property is it a family is it a rental property does there need to be a couple of hot water draw off points running at the same time? What's the flow rate to the property all boilers have a certain flow rate design and can only give enough hot water as what is entering the property hrough the cold water tap usally or garden tap usally best place to measure the true flow rate from.e.g. less than 10 liters a minute then a 24Kw would suit bearing in mind that 10liters a minute hot water is all you'll recievd from your hot tap. If it's less than 13 liters a minute then 30kw boiler may be the right choice for you. The amount of radiators isn't a massive concern when choosing a combi boiler. Its all based on your hot water needs! Which is like a water lottery depending on your area. If you're looking for a new boiler to be installed in your property. I'd be more than happy to come round measure the flow rate in your property look at your living situation and recommend a boiler for you. I install many of the top brands of boilers and I also install some budget brands of boilers as well,if you're in the West London area please don't hesitate to give me a call if you need just advice or you need a no obligation quote.

This unfortunately is not as easy as the question suggests. If you have a low flow rate ie litres per minute coming in off of your mains water say below 10 litres per minute then you may not even be able to have a combi boiler purely as they all have a minimum flow rate they work to effectively so that they can modulate correctly and be efficient or otherwise what's the point? Now bear in mind this is just a rough guide and there is more to it than this but say you had a flow rate of say around 11 lpm you could have around a 26kw combi boiler, then say you had around 16 lpm then you could have a combi boiler of around 30kw however this would probably only be suitable for 1 bathroom and 1 shower. If your flow rate was 18 to 20 lpm then you could go for a 40kw, depending on the manafacture most 40kw combi boilers can handle 2 bathrooms with showers depending on the size of the heat exchange within the boiler and the manafactures specification, however this isn't always garunteed. If you find that there isn't enough flow rate to your property to have a combi boiler don't despair as there are pumps on the market that will increase your flow rate to 12 lpm meaning you could then have a lower kw unit fitted. Alternatively if you have a massive flow rate and an incoming main of 3 bar or over with 2 or 3 bathrooms I would strongly recommend you have an unvented cylinder and system boiler.

The best combi for a 2-3 bed property is one that best matches , customers needs , customers budget but mainly it is dependent upon flow rate of the cold supply to the property as if you have a low flow rate fitting a high output boiler impractical, also heat loss calculations for the property also need to be carried out to determine central heating output requirements

The size of a combination boiler depends on several factors the mains inlet pressure how many people living in the property & the number of hot water outlets & if you shower or have a bath as this will affect what size boiler you would need. Having a too larger boiler is not cost efficient with the new condensing boilers. I recommend having a Gas Safe Registered heating engineer to advise you on what boiler would be most suitable for your hot water needs.

Depends on how many occupants. How many hot water outlets it will be serving. What the hot water requirements are. What the incoming water supply flow and pressure is. The size of the building. Always ask a qualified experienced engineer for a survey of the property before choosing the right option.

Whether it’s a one bedroom flat or a 3 bedroom house, combi boilers are sized according to the mains water flow rate coming into your property. If you have a low mains water flow rate for example of 9 litres per minute, a 24kw combi will easily handle that to give you sufficient hot water. There would be no added benefit at all of putting in a big 35kw combi, all this would achieve is a bigger hole in your pocket! Both from the cost of the boiler and the new gas run that would most likely be needed. Most houses are so well insulated these days so they don’t have the heat loss they did in the old days, so a 3 bedroom house with 10 radiators would only need 10-15kw for the heating so again a 24kw would be more than big enough for the heating side. Always get a gas safe registered engineer round to quote as he/she will best advise what boiler is suitable for your property.

The best Combi boiler for a 2-3 bedroom house really depends on a few factors. 1. You will need good mains water pressure to ensure a decent flow of hot water from your Combi boiler. 2. How many people might be wanting to use the hot water at the same time? If you have a large family and need to run multiple hot water outputs at the same time then maybe a Combi isn’t right for you. In my opinion it is best to contact a gas safe registered engineer and ask them to come to your home and talk thought your various options

The best combi for a 2-3 bedroom house would depend on the amount of showers or bathrooms, the flow rate and pressure would need to be sufficient before choosing your boiler. Providing based on one shower we recommend a Baxi 428 or 630 for a combi boiler efficient enough to suit, easy to use and maintain and up to 7 years warranty available, so great value for money.

We prefer to use a Baxi boiler, but to wander the question. It all depends on the hot water and heating requirements of the property and the occupants. What are looking to achieve and how many showers do you have in the property. We would be looking to possibly install a 30kw combi boiler or a system boiler with unvented cylinder if you have multiple bathrooms.

The best combi boiler for a two to three bedroom house will vary, I would go more by the way the occupants use their hot water. Generally, the hot water flow rate (litres per minute, at a given temperature rise) will depend on the kilowatt OUTPUT of the boiler. If a property only has one or two occupants with low water demand a 24 or 26 kWh model will suffice. If by contrast a family live there with large hot water demands and baths are needed quickly, then a 30-40 kWh model may be better suited. Bear in mind that the radiator requirement will almost always be met by the lower models as the radiators are not needing to be heated as quickly as tap water is.

Alot of companies thinks it solely goes on the Kilowattage of a boiler, but its also down to the LPM of the mains cold water incoming and boilers water supply. Generally though you'd be looking at around 24kw to 30kw boiler. Each company has their favourite boilers to fit and they will most likely have a higher warranty to offer their customers on said boilers. Theres also the options of the lower tier of boilers like Vokera and the higher tier like ATAG.

A 2/3 bedroom house depending on the pressure of the incoming mains water would need a 28-30kw boiler. There are plenty of options to choose depending on budget and requirements, the best thing to do would be to get a qualified engineer in to test you incoming supply and give you a quote.

The must suitable Combi boiler for any house depends upon the incoming mains pressure and flow rate. Any Combi boiler should be matched to the income mains so as to enable the correct hot water output. Any Combi boiler would be able to supply sufficient output to heat the central heating system in a 2-3 bedroom house but it would be a waste of money fitting a boiler that was capable of delivering 15 lpm if the incoming supply is only 10lpm.

Same as with a 4-5 bedroom property it will depend on number of bathrooms and water flow rate. Generally speaking a 2-3 bedroom will have around a 28KW combi in. There are many manufacturers giving different prices and warranties to suite the homeowners budget. An ATAG Economiser 27 will give you 12.6 litres per minute at a 35degree rise and 94% efficiency.

It really depends on the size of the house not all 2-3 bed homes are the same size or same amount of bathrooms. If you have one bathroom only maybe a Baxi 630 30kw combi comes with a 7 year warranty if you have two or more full bathrooms go for a Baxi Eco Blue advance 33kw , comes with a 10 year warranty

Probably a Potterton Gold 24 HE or a Baxi DuoTec 24 HE - These boilers are very efficient and the Baxi range are compact and they are very, very reliable. A 2 bedroom property with an average of 6-7 radiators would be fine with one of these boilers. On an average double panel size radiator the calculations are roughly 2 KW per radiator, and on a single rad they are roughly 1.5 KW. One of these boilers would be more than suitable. Also, take into consideration that every installer will recommend their own favourite brand to the consumer.
